there as only one setting, the 87 GN and T-Type had the same setup. The T-Type didn't get the all black treatment.

87 GNX had 15 psi.......


Thats all my 1 minute free goggle search allows......

Shall I bill you at $240 a hour for ther next minute?

hahahah do you take credit?

Something like 12psi IIRC, but that's ECU regulated. I think there's usually only 8psi in the vacuum actuator
